Quality Control for PGM Catalyst Components

What this topic covers

Loading uniformity, performance testing and traceability without manufacturing recipes.

Core energy-system ideas

Precious-metal loading should be measured accurately enough for both performance and material accounting.

Electrical and electrochemical testing can detect defective catalyst components.

Traceability supports recycling and root-cause analysis later in life.

Important tradeoffs

Catalyst-layer performance emerges from reaction kinetics and transport at the same time.

Material and performance evidence

Lower platinum loading can increase sensitivity to local transport or degradation effects.

Lifecycle perspective

Manufacturing scrap is part of platinum material accounting and can be an important recycling stream.
